    Per IOSPE it is the "small spotted Bulbophyllum" from SW China, named by a botanist abbreviated as 'Balakr' in 1970 ; that struck me as odd, since it is a plant ( not this example, but an earlier one in my collection) which I grew 10 years before that date ! The answer it seems is that it was a Cirrhopetallum from 1896 and only shifted into Bulbophyllum is 1970. Cirrhos' used to be those Bulbs with flowers in a radial pattern like spokes of a wheel - or daisy type ; but now are only the ones where the two lateral petals are joied togethr ( I think ! ). All the rest are now Bulbo's. Problem solved.

    This plant, one of two or three different clones in my collection, seems to have stronger coloured lips than usual, which may be a cultural thing.I like it.
    I know that some Paph growers for exampe think that growing their genus in low light leads to brighter coloured and larger flowers ; the downside is that it leads to fewer flowers too - and since many only have a single flower anyway, that means that they don't flower every year. Makes snse. So what do you do , increase the light and go for more flowers, but at the expense of flower size and colour ? That is the sourse I used to follow, but this year having been rather otherwise occupied after my 3 eye operations and my wifes surgery too, I never got around to putting on the usual final layer of shade, and most things are suffering from too much light ; this Bulbo' by the way was at the back of the bench, on the shady side, almost hidden by the large leaves of a Phaius, so it was an exception. But all this has had me thinking, and I plan to increase the level of shade, beyond what I have been using for many years now, when next Spring comes. Of course its too late in the year to think of doing so now - what is there will remain there until October as usual, but next March/April/May, I intend to put on maybe 50% more than this year.

    Any contributions of thoughts on the subject of light and depth of colour/size of flowers wilol be read with interest.

    Well, I will be interested to see how much more shade will add to the vibrancy of the color. I've never heard this before. I know that temperature seems to do this with some oncidium blooms. I have a Linda Isler 'Red' that will bloom very red when it is cooler in the greenhouse and much more brown-red when temps are warmer. The first time I noticed this was when it bloomed for us just after getting the orchid from a wholesaler in Hawaii. It came with buds about to open on one spike and a developing spike on the other side of the plant. The buds that opened were grown in a much warmer location at the time and were a beautiful brown-red. When the second set of buds opened after growing here for a bit, they were an intense red. Never considered it could also be caused by light levels... hmmm

    cheers,

    This is a very pretty bulbo. I like it just the way it is.

    My burr. Nelly Isler bloomed more brown than red during the end of the heat wave. It is probably getting more light, too, as it is outside and, for once, we are having a sunny summer.

    For better or worse, the taxonomy has been simplified; all are in the genus Bulbophyllum and there are no Cirrhopetalums (for the time being, at least). Kew has thrown in with the "lumpers".
    One experience I have had with light affecting color has been with Cattleya (Laelia) sincorana. I bought the plant in bloom with deep purple flowers. I grew and bloomed it once in bright light and the flower was washed out. I grew it in bright light, moved it to lower light when it came into bud, and the flower was a much deeper color. There may also be a temperature factor involved, but not in my growing conditions.

    Interesting thread and I know I am not much help here, but I have seen other flowering plants have a faded look in bright light so I could see the same with at least some orchids. They are still vivid colors to me also Geoff, which I do admire. AL
